Wireless sensor network (WSN) is a collection of a huge number of autonomous sensor nodes having capabilities such as sensing, processing, and manipulation. In any WSN, routing protocols are the backbone for performing all type tasks such as sensing, controlling, and transmission of packets in ubiquitous environment. In this article, a LEACH protocol with Levenberg-Marquardt neural network (LEACH-LMNN) is considered to analyze the overall network lifetime. The aim of LEACH-LMNN protocol comprises two parts: selection of cluster head node using LMNN approach and the second part is to locate the...
